The vast majority of homicide victims are male. In the US, the number is 78%. In the whole world, it is 79% [0].

and who are the vast majority of assault and rape victims?
According to TFA, the law wasn't written to ensure that. It's selective enforcement, with cops making judgement calls both about how loud is loud and who looks like they deserve a ticket.
Anecdotally, in midtown, this isn’t true. (The Jersey plate correlation is.)
Keep in mind that making one’s vehicle flatulate isn't cheap.
Rusted out exhaust pipes from road salt in NYC on cars will make them louder but nothing like what I'm describing. Basically makes them have an annoying low pitched rumble similar to what those stupid $40 ricer 'fart can' modifications would. Few orders of magnitude of a difference between loudness.
Additionally, at a time when the streets are seriously unsafe, this should not be a priority.
It is reasons like this that I am infinitely glad I left NYC for the woods of the West Coast.
EDIT: I would just like to add, if you feel that the streets of NYC are a safe place at night for women, children, or whomever, then I really feel like your opinion is very dismissive of people who have been seriously injured or killed.
